SHINGLING-BRAGKET.

Application filed April 20, 1916.

To all whom, it may concern:

Be it known that I, FRANK A. ADAMs, a citizen of the United States,residing at Ilion, in the county of Herkimer and State of New York, haveinvented certain new and useful Improvements in Shingling- Brackets, ofwhich the following is a specification.

This invention relates to certain new and useful improvements inshingling brackets.

The primary object of the invention is the provision of a bracketadapted to be readily clutched to the laid shingles of a roof and havinglocking means adapted for removably supporting a scafi'olding member inoperative position upon the roof.

A further object of the device is to pro Vide a bracket that is of smalldimensions but exceedingly strong in its construction having toothedjaws for engaging the shingles upon a roof, the jaws being locked intheir operative position by means of a scaffold supporting cam lever.

he present invention contemplates the provision of two identicalbrackets positioned in horizontal alinement in spaced relations upon apartially shingled roof and adapted for supporting a- 2X4 timberarranged across the said brackets and positioning the same for theaccommodation of the carpenter in laying the succeeding courses ofshingles thereabove.

With these general objects in view and others that will appear as thenature of the invention is better understood, the same consists in thenovel construction, combination and arrangement of parts hereinaftermore fully described, illustrated in the accompanying drawings, and thenclaimed.

In the drawings forminga part of this application and in which likedesignating characters refer to corresponding parts throughout theseveral views: Figure 1 is a side View of one of the bracketsoperatively positioned upon a partially shingled roof, the shingles androof .board being shown in vertical section and a scaffolding memberbeing illustrated in end elevation partially broken away mounted uponthe bracket, the latter shown in dotted lines in its released position.Fig. 2 is a top plan view of the device. Fig. 3 is a top plan view of aportion of a shingled roof with two of the brackets and a scafloldingmember operatively arranged thereon, the said scaifolding member beingbroken away, and Fig. 4: is a perspec Specification of Letters Patent.

tive view of the bracket with the movable jaw thereof removed.

The present bracket being employed in connection with a shinglingscaifolding, the same is herein illustrated with reference to a pitchedor inclined roof 10 having a plurality of courses of superposed shingles11 secured thereon in the usual manner, one of the brackets beingillustrated in Fig. 1 of the drawing in its operative position engagingthe uppermost course of shingles and being adapted to support ascaffolding member 12 whereby the shingling of the roof may be completedby applying further transverse courses of shingles above those hereinillustrated.

The present bracket consists of a base or plate 13 having a toothed jawportion it at one end thereof and inclined rearwardly projecting shingleengaging calks 34; at its other end. A movable jaw 15 is pivoted to anupstanding post 16 carried by the said plate, the said movable jawhaving a toothed inner face 17 arranged in opposition to the plate jawteeth 14. A transverse shoulder 33 is spaced rearwardly from the teeth14, being in alinement with the forward face of the post 16, the saidshoulder and face lug constituting an abutment for the shingle 11 whenthe device is positioned in engagement therewith. The movable jaw 15 isprovided with a slot 18 fitting over the upper curved end of the post16, the movable jaw being pivoted to the said post by means of a bolt orpin 19. A substantially rightangular operating lever 20 is pivotallymounted to a lug 21 centrally carried by the plate 13 in alinement withthe aforementioned post 16. The movable jaw 15 is provided with alongitudinally inwardly extending centrally arranged notch 22 slightlywider than the slot 18 and positioned rearwardly thereof and opening atthe rear end 23 of the said movable jaw, the main or upright arm portion24- of the lever 20 being freely positioned within the notch 22 andfiatly'engaging the inclined forward end 25 of the said notch when thelever is in its inoperative forward position. Substantiallytriangular-shaped operating wedges 26 are carried at opposite sides ofthe angle portion of the lever 20 in the form of lateral projections andthrough which the pivot pin 27 is extended which unites the said leverwith the lug 21. The base faces 28 of the wedges 26 are in flatengagement with the inner faces of the bifurcation portions 29 of themovable jaw 15 when the lever 20 is inoperatively positioned. It willthus be evident that by elevating the lever arm 2% or in other words,moving the lever upon its pivot 27 moving the arm 2 1 in a directionaway from the plate 13, the outer curved ends 30 of the wedges willbecome engaged beneath the bifurcations 29, thus forcing the outer end23 of the movable jaw 15 away from the plate 13 and consequently forcingthe toothed portion 17 of the movable jaw toward the toothed portion 14of the said plate and whereby a shingle 11 may be firmly clamped betweenthe said toothed surfaces. The opposite end of the lever 20 from the arm24 constitutes a heel portion 31 which flatly engages the plate 13forming an abutment when the device is in its operative clampedposition. The device is preferably formed of metal, while the movablejaw 15 may be slightly resilient if desired. The forward face of thelever arm 24 is provided with a spur 32 adapted to engage within ascaffolding member or timber, such as the 22rd 12 illustrated in Figs. 1and 3 of the drawing. l/Vhen the scaffolding member or timber 12 is soarranged upon the arms 24 of two spaced brackets attached to the samecourses of roof shingles, the lower corner of the timber will be inengagement with the upper faces of the movable jaws 15, therebypreventing the levers 20 from being moved to their releasing positionsprior to the removal of the said timber therefrom while the calks 34engaging the shingles 11 prevent the bracket from slipping and with thejaws 14: and 17 firmly position the structure.

The complete operation of the device will be at once apparent from thisdetailed description thereof, the manner of attaching the two bracketsin spaced relations upon the roof shingles having been alreadydescribed, as well as the arranging of the timber 12 thereupon. Thecarpenter upon the roof as well as the bundle of shingles to be employedin the work are supported by means of the timber 12, a strong andserviceable support for the operator being thus arranged rendering theshingling operation less hazardous as well as protecting the supply ofmaterials used in the work.

While the form of the invention herein shown and described is what isbelieved to be the preferred embodiment thereof, it is nevertheless tobe understood that various forms, modifications and arrangement of theparts may be made without departing from the spirit and scope of theinvention as claimed.

WVhat I claim as new is z 1. A shingling bracket comprising a base platehaving a forwardly arranged toothed portion, a post centrally carried bythe said plate adjacent the toothed portion thereof,

a lug upon the said plate centrally of the latter and rearwardly of thesaid post, an angular operating lever pivoted upon the said lug andhaving opposite triangular wedge projections, a movable jaw pivoted tothe said post and having a bifurcated rear end, the bifurcations ofwhich span the said lever and are arranged in abutting engagement withthe said projections when the device is in its operative. position.

2. A shingling bracket comprising a base plate having aforwardly.arranged toothed portion, a post centrally carried by the saidplate adjacent the toothed portion thereof, a lug upon the said. platecentrally of the latter and rearwardly of the said post, an angularoperating lever pivoted upon the said lug and having opposite triangularwedge projections, a movable jaw pivoted to the said post and having abifurcated rear end, the bifurcations of which span the said lever andare arranged in abutting engagement with the said projections when thedevice is in its operative position, thesaid lever having a heel at oneend thereof in abutting engagement with the said plate when the deviceis operatively positioned and being further provided with an operatingarm at its opposite end, aprojecting spur carried by the said arm, thesaid movable jaw having teeth upon its inner face opposed to the forwardend of the said plate.
